    What to do if my Northern Lights Inverter engine overheats?
    • J
      Jonathan GrahamAug 21, 2025
      If your Northern Lights Inverter engine overheats, try reducing the electrical load first. Ensure the coolant level is adequate by filling the tank or radiator. Inspect hoses for leaks and loose connections. If you have a marine set, make sure the keel cooling tubes are free of paint. Consider flushing the cooling system and checking the thermostat.

      Matthew JonesAug 23, 2025
      If your Northern Lights Inverter engine is hard to start or won't start, first check the fuel level in the fuel tank. Check the electrolyte level and condition of the battery. Clean and tighten all battery connections to address any excessive resistance. Ensure you are using the proper type of fuel and that the crankcase oil has the correct viscosity. If there's water, dirt, or air in the fuel system, drain, flush, fill, and bleed the system. Clean or replace the primary fuel filter element and replace the secondary fuel filter element.
